摘　　要：文章以农林废弃物生物质为原料,运用热压法对前驱物的结构进行辅助优化,成功制得氮掺杂碳材料PNC。该方法强化了生物质原料与添加剂的结合,优化了催化剂结构,提高了热解效率。电化学测试结果表明,PNC催化氧还原反应(ORR)的初始电位和极限电流密度与商业Pt/C相当,而稳定性和抗甲醇毒化性能优于Pt/C。该研究为生物质基电催化剂前驱物的制备提供了一条新途径。A nitrogen-doped carbon material PNC is prepared from agricultural and forestry waste biomass by assisting in optimizing the structure of the precursor through hot-pressing method.The hot-pressing method strengthens the binding degree of biomass with additives to improve the pyrolysis efficiency and the structure of the catalyst.The electrochemical test shows that the ORR initial potential and limit current density of PNC are similar to Pt/C.Meanwhile,PNC shows better stability and methanol-tolerant performance than Pt/C.This paper provides a new way for precursor treatment of biomass-based electrocatalysts.
